This happens due to the way cookies work. If you always visit the HTTP or always visit the HTTPS version, your cookies will remain intact. However, if you log in with HTTPS and then visit the HTTP version, your browser will remove the cookie for security (it would be bad to send an intended-to-be-secure cookie over an insecure connection). I had changed the inter-board links to use the HTTPS version, which is probably triggering this behavior when you manually visit the HTTP version. I just now fixed those links to be protocol-relative, so you'll be directed to the same version of the site that you're already on. Apologies for the inconvenience. To make sure you get the secure version, I suggest updating your bookmarks/history to be HTTPS.

Still not working. I even deleted my cookies, updated my url etc. Still the same.

Simply typing in https://pckf.com won't work. It didn't work for me either until I changed my bookmark to include the rigeltechnical domain without relying on the redirect.

That appears to be an artifact of the Great UTF8 Butchering of December 2016. One post involving "jroc" contained some bad characters that made PHP extremely confused. (Navigating directly to that page also caused the error.) I just edited it to delete the offending text. Thanks for the report!

Andy probably took down his server for good. I have still been unable to reach VitaminZach by e-mail, so if anybody has other contact with him, it would be great if you could notify him about the situation.

I have an issue with the new forum. I need to open all the topics that are lit in red in order to mark all the forum sections as red.

In the old forum this wasn't an issue. I only needed to visit a sub section of the forum without the need to open all the topics that have new posts. And the next time I visit the forum and if no new topics were present since the last time I visited it, everything would indicate that there are no new topics. The thing in the new forum is it is getting annoying, since there are topics that I'm not interested to open, but I need to open them all in order to mark the whole section as red. Otherwise the sections will stay in red and every time I will need to open the forum sections to see if there are new topics.
